im a new website developer and i dont have much experience with this subject.

I made a new website for a customer using wordpress ( also the previous uses wordpress)

My question is , in the old website the links are like this

Page -> www.[mywebsite]/page-name
Portfolio -> www.[mywebsite]/portfolio/portfolio-page
blog-> www.[mywebsite]/blog-page

which was wrong because the blog pages are not made with posts but with wordpress pages thats why the blog page doesnt have a /category/ before its name.

in the new website the blog posts are made with posts instead with the category

My issue is, that right now if i set the permalinks it shows like this

Page -> www.[mywebsite]/page-name
Portfolio -> www.[mywebsite]/portfolio/portfolio-page
blog-> www.[mywebsite]/**blog-category**/blog-page

and if i make the permalinks as simple it shows like this

Page -> www.[mywebsite]/page-name
Portfolio -> www.[mywebsite]/portfolio-page
blog-> www.[mywebsite]/blog-page

so my question is, is there any way that i make the permalinks of the blog to NOT show the category of the posts but show the category of the portfolio ?

if this has been answered before im very sorry. Thanks for your time.
